When we looked up the tickets on SBB.ch from Engelberg to Milano Centrale, it showed there were two transfers. The first one was in Luzern and the second one was in Lugano.
After we bought the tickets, we noticed in the itinerary there was a 4 min connection (11:26 – 11:31) in Chiasso to get on to TRENORD 25517 to Milano Centrale.
Can you please let me know if we will have to change platforms and if we have enough time for “ticket inspection” and “check-in”?
